Madonna has revealed that producer Pharrell Williams reduced her to tears during the making of her recently-released ‘Hard Candy‘ album.

“He made me cry. I’ve never told that to anybody!” the singer said during an interview in Cannes this week. “You know when you get angry with someone and you start spitting snot?”

In an interview with ABC’s ‘Nightline’ TV show which aired last night (May 22), Madonna explained she was in a sensitive mood, and did not like the way the producer spoke to her while she was recording vocals.

“I was in a sensitive mood, I was singing and I didn’t understand the rhythm that he wanted me to sing in, and he was kind of giving me a hard time and I was sort of taken aback by the way he was talking to me, so I said 'You know what? we need to talk'”, she said “So we went upstairs and I’m like ‘You can’t talk to me that way!’ and then I just burst into tears and he was like ‘Oh my god, Madonna has a heart!’, and I was like ‘What?!’ and I started crying even more, and we had it out. Now I love him and we make great music together, but I think we had to go through that.”

The singer is in Cannes to promote her documentary ‘I Am Because We Are’ during the film festival.
